Yoga Bolsters are mainly used to lift and support the body to promote deep, restorative type poses. The firmer a yoga bolster is, the less sinking feeling you will get when you lie on it. What is important is that the yoga bolster runs the entire length of your spinal column. You should feel muscular and tension relief as your chest, abdomen and back begin to relax and your rib cage begins to open more. In this way you can feel your breathing and monitor inhale and exhale.
Yoga Bolsters come in different sizes and materials. Depending on the exercises you would like to perform you choose your ideal Yoga Bolster. Smaller and thinner Yoga Bolsters are also called Pranayama. They are round and ideally quite firm. Yoga Bolsters also come in larger sizes, often round but sometimes rectangular as well. They support your body during restorative yoga poses such as savanasa and reclined hero.
